Generally, the average nucleic acid produced by human body through food intake every day is only about 0. 5~ 1 g. In order to supplement nucleic acid and maintain health, the World Health Organization suggests that adults need to supplement exogenous nucleic acid 1- 1.5g every day. However, for some people who are particularly lacking in nucleic acid, such as people with low immunity, patients with functional and degenerative diseases and the elderly and infirm, the number of nucleic acids that need to be supplemented should be increased, and some people need about 2 grams a day.
Nucleic acid is a macromolecular substance in biological cells, which consists of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Deoxyribonucleic acid (DNA) mainly exists in cytoplasm and is an important core substance of cells. Because of its acidity, scientists call it nucleic acid.
Firstly, a gene is a functional fragment with genetic information on the molecular chain of deoxyribonucleic acid (DNA), which contains all human genetic genes. In other words, DNA is the carrier or ontology of genes.
In addition, about 600 billion cells die and regenerate every day. In the process of alternation between old and new cells, the nucleic acid (DNA) in cells must copy genes. In addition, in daily life, human cells are often damaged by various physical, chemical or biological factors in the living environment. In the final analysis, it is genetic damage. Therefore, it is necessary to repair the damaged genes in time in order to make the metabolism and life activities of the human body go on normally. Nucleic acid (gene) needs raw materials in the process of replication and repair, and this raw material is the structural unit of nucleic acid-nucleotide, nucleoside and so on.
Exogenous nucleic acids, whether DNA or RNA, are digested and degraded into nucleotides, nucleosides, phosphoric acids and bases, which provide raw materials for gene replication and repair. So from this perspective, nucleic acid nutrition is gene nutrition.
Nucleic acid is closely related to human immune function. When the nucleic acid in the body is sufficient, the immune function is enhanced. On the contrary, when the human body lacks nucleic acid, the immune function declines, and various diseases will follow.
It is found that supplementing enough nucleic acid from outside can promote the development of human immune organs and repair damaged immune organs. The decomposition products of nucleic acids, such as adenosine triphosphate (ATP), cyclic adenosine phosphate (cAMP) and cyclic guanosine (CGMP), can enhance the physiological function of immune organs and promote the proliferation and vitality of T cells, macrophages, natural killer cells, lymphocytes and other immune cells. In addition, the products of nucleic acid decomposition can also promote the secretion of immune substances in human body, such as interleukin -2 (IL-2), interferon, immunoglobulin, etc., thus playing a good immunomodulatory function.
